Develop my wordpress template

Hi, I have a site to watch and upload videos and use the Toroplay template, and I want to develop the template and add some improvements and features that are missing: - Adjust the episodes slider at the bottom of the episode to show episodes arranged starting from the previous episode of the current episode (from right to left). - Above the episodes slider, add the next/previous episode buttons, and in the space between them, add a search bar for episodes so that they appear in the episodes slider so that the user displays any episode he wants by writing its number. - Possibility to pin Series/Seasons/movies on the home page. - Developing the research to include seasons instead of just series. - Solve the problem of the disappearance of the thumbnail image when dragging from the TMDB site, where after editing the episode, the image disappears and you have to set it again. - The possibility of showing the name of the custom season on the season page under names each season with the name of the series + the season number. - Preparing a registration system for members that is separate from the basic registration system on the site and is only at the rank of a subscriber, and it cannot be promoted to a supervisor or an admin, and a personal file is prepared for each member. - Availability to add the series to favorites, watch later, or previously watched. - Add related anime below the episodes. - When adding links at once, the ability to specify viewing links and download links (the feature is present but does not work well) - The ability to show specific notes for each server, such as “the server is down” or “this server shows ads that we have nothing to do with and we do not make money from them” ... - Possibility to show a mark on series, seasons, and movies such as (completed - in production - last...) - Filter in the lists of series and movies. - The possibility of activating the dark mode of the site. - Do any other work I may ask to improve the template - Nice touches on the design to make it look like a different template. I want a professional person or company who know what to do and what I'm talking about.
